/* ============================================================
   Site navigation (.pnav) — lifted verbatim from premium.css so a page
   can carry the shared navbar without loading the whole design system
   (premium.css also redefines .shell / .section / .eyebrow, which would
   collide with a page that has its own styles).

   The tokens the nav needs are scoped to .pnav itself, so they cannot
   leak into the host page's own :root variables.

   Keep in sync with premium.css if the navbar there changes.
